very quickly and you may not get exactly 400Wh energy.On the ipside,if you’re charging devices
that draw power slowly(a small TV),you will get closer to 400Wh from the portable power supply.If
you’re experiencing shorter runtimes,you may need to check the device’s power requirements, refer
to TROUBLESHOOTING which will be discussed below.
■ Cold Weather Usage
Cold temperatures(below freezing) can impact the battery capacity of the portable power supply.
If you are living in sub-zero conditions,you can drain power from it.NEVER charge it in the sub-zero
conditions,which will damage the lithium-ion battery and battery capacity may not be recovered.
Low Temperature Charging Protection:In the sub-zero condition,the portable power supply would
stop being charged automatically.It starts being charged again when temperature is over 5
℃.
Low Temperature Discharging Protection:In the environment which temperature is -20
℃
,it would
stop AC and DC output,then shut itself down in 15 seconds automatically;and it can output again
when the temperature is over -15
℃
.
